Other studies (Marchioni & Shneiderman 88)

• Hyperties Dataset

  • 14 of 16 subjects asked to search for factual information used the alphabetical index
  • but it did not seem to have a topic index -- only embedded hyperlinked terms
  • No query formulation either

• Museum Dataset

  • In undirected use, 2/3 of all selections via hyperlinks
  • When asked to search for specific facts, index users were much faster than link users
  • This difference became smaller with longer use
